# Release Note Coverage — Record Quality Audit + Secondary-Measure Weighted Mean

> Release Note Coverage — Record Quality Audit + Secondary-Measure Weighted Mean is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-24).

Runs a record quality audit and secondary-measure weighted mean analysis on release note coverage data (documented_changes vs released_changes) for up to 200 rows, returning two independent analytical reports.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability release-note-coverage-record-quality-audit-secondary-measure-weighted-27cc01ff -d '<json body>'
```

Example prompt: Can you run a record quality audit and weighted mean analysis on my release note coverage data? I have rows with documented_changes and released_changes fields — use 'documented_changes' as the primary field, and I'll supply up to 50 rows across two document groups.

## When to prefer this

Choose this endpoint when you need to simultaneously audit the data quality of release note coverage records AND compute a weighted mean on one of the numeric coverage fields, all in a single $0.01 call. It is best suited for offline/batch analytical workloads on up to 200 pre-collected rows where no live data lookup or external prediction is needed. Prefer this over separate audit and statistics endpoints when you want two coordinated reports sharing the same analytical engine on the same dataset.

## Known failure modes

- Empty or missing rows array returns validation error
- More than 200 rows submitted exceeds limit and is rejected
- Invalid date format (not YYYY-MM-DD) causes row rejection
- Missing required fields (row_id, document_group, date) causes schema validation failure
- Null values in both documented_changes and released_changes may degrade weighted mean calculation
- Invalid field enum value (not 'documented_changes' or 'released_changes') returns error

## How this service works

Release note coverage — Record quality audit + Secondary-measure weighted mean: Record quality audit + Secondary-measure weighted mean for supplied release note coverage records (documented_changes, released_changes). Up to 200 rows; 2 independent reports using shared local analytical engines. No live lookup, prediction, professional assessment or external action. 0.01 USDC includes 2 supplied-data reports for up to 200 rows.

## Output

Returns two independent analytical reports for the supplied release note coverage rows: (1) a record quality audit identifying data issues, missing values, and anomalies in the dataset, and (2) a secondary-measure weighted mean calculation for the selected field (documented_changes or released_changes), potentially grouped by document_group or date. No external data is fetched; all analysis is performed locally on the supplied rows.
